FAQ
What .NET versions do you work with?
.NET 6, 7, 8, and 9 (LTS recommended). I can support legacy .NET Framework 4.x if your project needs it — just mention this in your message.
Do you provide full source code?
Yes, complete, well-commented source code is included in every package. You own it outright on delivery, including commercial use.
Can you work with my existing codebase?
Absolutely. Share your repo (a sanitized version is fine) and I'll match your existing patterns, naming conventions, and architecture decisions.
Which databases do you support?
MongoDB (preferred), Microsoft SQL Server, PostgreSQL, and Redis. Others available on request but please message me first to confirm.
What if my project doesn't fit a package exactly?
Send me a message before ordering. I'll review your requirements and either build a custom offer or suggest the closest package with the right extras. Better to scope precisely than guess.
